The discussion of the link between  personality types  and  strategic change by scholars today  is compounded by the  contradicting findings as how personality types influence implementation of strategic change. While some studies reveal positive correlation between personality types and the strategic change implementation initiatives, some studies indicated negative relationships. In Kenya and specifically the Judiciary of Kenya, the rationale to understand how personality affects the implementation of change is anchored on the fact that that since the promulgation of the constitution of Kenya 2010, the Judiciary of Kenya has been reorganizing and carrying out changes to operationalize the implementation of the constitution of Kenya 2010 within its structures. The objectives of this study were to investigate the influence of the personality types on the implementation of strategic management in the public institutions in Kenya, establishment of how agreeableness, openness, neuroticism and extraversion influenced the implementation of strategic changes at the Judiciary of Kenya were the specific objectives of this research. This study sought to benefit the ongoing or future strategic changes at the Judiciary of Kenya. It also sought to benefit other government institutions and provide strategic think-tanks and policy developers with information they needed for policy development and implementation. Further, the study aimed at benefitting future researchers with a point of reference. The research design adopted by this study is a descriptive research design.  The study target population was 5987 employees whereas the sample size was 362 employees of the Judiciary of Kenya. This study used questionnaires to collect primary data. The data collected was analysed using the SPSS software version 20.0.
